Description

Technical Field

[0001] The utility model relates to agricultural technology, in particular to an organic fertilizer granulator and an organic fertilizer granulator device for making organic fertilizer from solid excrement produced by aquaculture. Background Art

[0002] The die roller forming parts, the core working parts of biomass pelletizing equipment, can be divided into ring die forming and flat die forming. As a concentrated feed forming technology equipment, it is relatively mature at present. However, as a straw fiber pellet feed for ruminants such as cattle and sheep, and straw, sawdust and mushroom residue biomass pellet fuel, it is not yet mature in other fields. There are still problems such as low output, high equipment failure rate, easy blockage of die holes, poor forming rate, and high cost of wearing parts. The pressing and forming of biofertilizer is still in its infancy.

[0003] At present, the more mature feed pellet machines are mainly used to make animal pellet feed. The raw materials are mainly composed of corn, bran, bean cake and other materials. They are characterized by less impurities, greater oiliness and cohesiveness. In the process of making feed, in order to maintain the quality of feed and facilitate storage, all materials with a moisture content of less than 14%, sieved and crushed by hammer mills, and basically the same particle size are mixed and granulated to ensure the quality of pellet feed. However, there are still many biomasses with high moisture content (about 16-25%) that cannot be sieved and crushed (easy to block the sieve holes), contain longer fibers, and have more impurities with less oiliness and cohesiveness (such as bulk bio-organic fertilizer), which need to be extruded into particles for field application. Therefore, it is necessary to conduct a comprehensive analysis and study on the existing feed pellet machines, select a pellet machine with a suitable extrusion molding principle, and make adaptive improvements to key components such as extrusion molding to meet the requirements of bio-organic fertilizer particle molding.

[0004] The existing organic fertilizer granulation technology is mainly based on ring die extrusion granulation, which consumes huge energy. There is an urgent need for technology and equipment that is more suitable for biomass granulation to promote the application of bio-fertilizer, improve the living environment, improve soil structure, and improve crop quality.

[0019] The beneficial effects of the utility model are:

[0020] The utility model has low energy consumption, high working efficiency and broad market application prospects, including:

[0021] 1) Using flat die granulation, under the extrusion of the moving roller, the raw material moves to the die hole of the fixed flat die. During the movement, it overcomes the resistance of the die hole and deforms, so that the raw material in the die hole forms particles under the action of multiple pressures;

[0022] 2) The threaded structure is used to solve the problem of rapid adjustment of the gap between the moving roller and the fixed flat die. In the granulation process, in order to improve efficiency, there should be no gap between the moving roller and the fixed flat die surface in theory. However, in the actual extrusion process, due to the resistance of the raw material, the moving roller and the fixed flat die will be separated by the extruded raw material, causing elastic deformation of both the moving roller and the fixed flat die. At the same time, the outer surface of the moving roller and the surface of the fixed flat die will wear rapidly. After working for a period of time and being severely worn, it is necessary to quickly adjust the wear gap between the two.

[0023] 3) It has an overload override function. In order to protect the motor and improve work efficiency due to uneven feeding process and instantaneous thickening of materials causing motor overload, an overload energy storage device is set up based on the analysis of the stress during the granulation process. It can release energy when the machine is overloaded and overcome the overload moment.
